Context

• These entries reflect an equity award (RSUs) and routine tax withholding (code F) rather than an open-market sale or purchase by the insider. The RSUs are slated for future delivery in three annual tranches (2027–2029). The amendment corrects the withholding amounts; the transactions do not by themselves indicate a change in the insider’s view of the company.
